@MaxBed4d do you think you could lead this effort?

This might require a bit more planning
In SKC, we build the image as a prerequisite job (called here, workflow here)

So that runs every time the workflow is triggered. That's necessary for SKC because the changes to be tested get baked into the image. In this case we just want the latest stable image. We can't just pull the most recently built image because that might've been built from a feature branch, not main.

So we can either:

1. Rebuild the image from the main branch of SKC every time we run this workflow. (Easy, less efficient)
   OR
2. Change SKC so when a PR gets merged into main, we give it some "latest" tag, and we reuse that (Harder, more efficient)

I'm leaning towards option 1, since the efficiency gains are minimal and I don't think it's worth the extra dev time. At some point if the scope of this repo grows it might become worth it but we'll deal with that if/when it happens
